Williams 9-Day EMA Breakout Trend Strategy

Summary

This short-term trend-following method uses a 9-period exponential moving average (EMA) as its directional reference. A candle opening below and closing above the EMA signals a long setup; a candle opening above and closing below signals a bearish setup. The accompanying source describes placing a stop order at the signal candle’s high for a long entry, and using the signal candle’s low as an exit level. The prose description instead refers to entry at the close and an exit from an earlier long position, so implementation details are not fully consistent.

The document explains the rules and suggests that an EMA can filter small price moves, but it provides no performance results or comparative evidence. It identifies likely limitations: whipsaws around the average, transaction costs and slippage, and a fixed period that may not suit every market. It proposes additional filters and more explicit risk controls as possible refinements. The stated backtest setup concerns BTC/USDT futures over a short date range, but no outcomes are reported.

Key ideas

• A 9-period EMA acts as the reference for identifying directional price crosses.
• A candle crossing from below to above the EMA signals a long setup, while a cross from above to below signals bearish direction.
• The prose and source code differ on entry and exit mechanics, so the exact order behavior needs careful interpretation.
• The document flags whipsaws, trading costs, slippage, and limited risk controls as important shortcomings.
